WEBVTT EXCEPT ON 28 WHERE YOU'RE A LITTLE SLOW HEADING NORTHBOUND. WENDY AND ANDREW SAM, THANKS SO MUCH. CREWS HAVE BEEN MAKING ROUNDS CLEARING THE STREETS AND PUTTING DOWN SALT AS WE HEAD BACK BELOW FREEZING. MATT BELANGER FOUND ONE COMMUNITY WHERE THEY ARE ASKING WHERE'S THE SALT AND MATT IS LIVE IN WEST VIEW TONIGHT. Reporter: WENDY,ED A WEST VIEW TO THE LIST. THEY RAN OUT OF ROAD SALT HERE THIS MORNING, AND NATIONALLY THE DEMAND FOR SALT IS HIGH BECAUSE OF THE WAY THIS WINTER HAS BEEN. COMMUNITIES ARE SCRAMBLING. OFFICIALS ARE FRUSTRATED, AND DRIVERS ARE DISGUSTED. SOMETIMES A PICTURE IS ALL YOU NEED, AND TONIGHT THIS EMPTY SALT DOME IN WEST VIEW TELLS THE STOREY. THAT'S WHAT I SAID. Reporter: PUBLIC WORKS MANAGER JOE ASSISI SAYS THEY RAN OUT OF SALT EARLY THIS MORNING. YOU JUST BARELY MADE IT. ORDERED 500 TON TWO WOULD EXAGO AND STILL WAITING FOR THAT 500 TON. Reporter: THEY HAVE RECEIVED A SMALL AMOUNT OF SALT FROM NEIGHBORING ROSS TOWNSHIP AND MIXING IT WITH LOTS OF ANTI-SKID MATERIAL TO TRY TO KEEP ROADS SAFE AND THEY ARE EXPECTING A SMALL SALT SHIPMENT LATE TODAY AND LIKE MANY COMMUNITIES PEOPLE HERE ARE LEFT WONDERING WHERE'S THE SALT. THIS ISN'T ROAD SALT BUT YOU'LL GET THE IDEAS. LET'S SAY THESE CANS REPRESENT THE SUPPLY OF SALT AT THE SOURCE. EVEN BEFORE WINTER BEGINS, SALT COMPANIES TAKES SUPPLIES OF SALT AND MOVE THEM TO STRATEGIC LOCATIONS ACROSS THE COUNTRY. WE'LL MAKE THIS WESTERN PENNSYLVANIA AND THEY BASE THIS ON ESTIMATES OF HOW MUCH THEY THINK WILL BE NEEDED. THE PROBLEM IS WITH SO MANY STORMS AND SO MUCH SALT BEING USED THIS WESTERN PENNSYLVANIA SUPPLY IS GONE, AND SALT COMPANIES ARE STRUGGLING TO DELIVER ENOUGH SALT TO KEEP UP WITH DEMAND. EVERYBODY WANTS SALT AND WE CAN'T GET IT DELIVERED. Reporter: MEANWHILE, DRIVERS ARE BEING WARNED IT'S MORE IMPORTANT THAN EVER TO PREPARE FOR SLICK CONDITIONS. CHECK THE EQUIPMENT ON YOUR VEHICLE, MAKING SURE YOU HAVE WASHER FLUID AND MAKING SURE YOUR TIRES ARE ADEQUATE FOR THE SNOW. Reporter: INTERESTINGLY, MORTON HAPPENS TO BE THE SAME COMPANY THAT PROVIDES WEST VIEW WITH ROAD SALT, AND THAT COMPANY ISSUED A STATEMENT TO CHANNEL 4 "ACTION NEWS" SAYING THEY HAVE BEEN OVERWHELMED BY ORDERS, AND THEY ARE DOING THEIR BEST TO MAKE DELIVERIES. HOWEVER, OUR REQUEST TO MORTON AND OTHER SALT PROVIDERS FOR DETAILS ABOUT WHY THIS IS PROVING TO BE SO DIFFICULT
